In contrast to nicotine vapes, a quality cannabis vapes should contain only cannabis oil and terpenes. Terpenes are the oils that give each plant – and in this case vape – its distinct aroma. A typical cannabis vaporizer might contain as much as 80% or more THC, leaving little room for much else. Every batch is tested and certified to be solvent free. Nicotine vapes, on the other hand, contain only about 4% nicotine and rely on a carrier solvent like propylene glycol or vegetable glycerine to give it enough liquid to work in an atomizer.
There were recent reports of teens getting sick from nicotine vapes, and the culprit was discovered to be Vitamin E oil used as carrier solvent in certain black market vapes. When you buy a THC vaporizer from a licensed dispensary in New Mexico, you are guaranteed to have a clean product without any carrier solvents.
